I have a custom board where a speaker is connected to ADC and I use two oneshot timers to control the sound. I have no buzzer. A library in this PR helps me split parsing RTTTL string from actually making the sound. @ghnotgood ahh Ok, understood, probably you mean DAC instead of ADC! So, did you implement a kernel driver to control this speaker over DAC and timers? It should be nice to very it integrated into mainline to be used as reference. -- This is an automated message from the Apache Git Service.
